American Foreign Policy since World War II has long set the standard in guiding students through the complexities of the field. This twenty-first edition features three new chapters that examine the aftershocks of the Arab Spring and the revival of power politics and discuss the implications of a changing American policy under the Trump presidency. Providing the historical context students need, this book helps them to grasp the functions and frequent dysfunctions of the nation’s foreign policy agenda with historical insight into modern policy context.
